Abstract
Abstract : The conditions under which N,N-bis(2-cyanoethyl) formamide (CEF) can be used as a liquid phase for the gas chromatographic separation of aromatics from the other components of motor gasolines having final boiling points no greater than 486F have been determined. A multiple-oven gas chromatographic system employing an isothermal CEF column, appropriate valving, a liquid sampling valve, and a temperature-programmed Dexsil 300 column has been used to provide analyses of the aromatic and the saturate-olefin fractions of gasolines. Highly precise volumetric analyses are made of the benzene, toluene, ethylbenzene, m+p-xylene, o-xylene, isopropylbenzene, and C9+aromatics using a direct calibration method. Procedures are also provided for the determination of the boiling-point distribution of both the aromatic fraction and the saturate-olefin fraction of the gasolines. Provisions for extending the procedure to higher boiling-point materials are discussed. (Author)
